Office Action

§102 §112 §Other
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim3 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 3 recites “a light scatterer provided around the diffuser.” However, the diffuser is alternatively recited in claim 1 and thus there is insufficient antecedent basis for the limitations recited in claim 3. Appropriate correction is required. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1, 2, 4-6 are rejected under 35 U.S.C. 102a1 as being anticipated by Jorgensen US 2017/0205051. In regard to claim 1, Jorgensen teaches light source apparatus comprising a first light source 305 and a second light source 303; an irradiation portion 307 irradiated with first emitted light from the first light source and second emitted light from the second light source; and at least one of a condenser 323 arranged between the first light source and the irradiation portion to condense the first emitted light or a diffuser arranged between the second light source and the irradiation portion to diffuse the second emitted light (see fig. 3a,[0053-0055]). In regard to claim 2, Jorgensen teaches a light shield 310 provided around at least one of the condenser or the diffuser. In regard to claim 4, Jorgensen teaches colors of the first light source and the second light source are different [0054-0055]. In regard to claim 5, Jorgensen teaches the irradiation portion includes a first optical unit that controls the first emitted light and the second emitted light, or includes the first optical unit and a second optical unit arranged between the first optical unit and an object to control light emitted from the first optical unit (see fig. 3a). In regard to claim 6, Jorgensen teaches a projector 322 that projects light emitted from the light source apparatus.
